脯氨酰羟化酶抑制剂对PC12细胞SDF-1α表达的影响
Effects of prolyl hydroxylase domain inhibitors on SDF-1α expression in PC12 cells
摘要
Abstract
Objective To investigate the effects and underlying mechanisms of prolyl hydroxylase domain (PHD) inhibitors on the expressions of SDF-1α in PC12 cells.Methods Cultured rat pheochromocytoma PC12 cells were treated with different concentrations of PHD inhibitors cobalt chloride(CoCl2),desferrioxamine (DFO) or dimethyloxalylglycine (DMOG),respectively.Cell viability was determined with cell counting kit-8 (CCK-8);the expression of SDF-1α mRNA was detected with quantitative real time PCR;the expression of HIF-1α and SDF-1α protein was measured with Western blotting and ELISA assays,respectively.Results CCK-8 showed that low concentration of CoCl2 promoted cellular growth;however,DFO,DMOG and higher concentration of CoCl2 inhibited cell growth with concentration increasing.The mRNA level of SDF-1 α was down regulated in a concentration dependent manner by DFO,CoCl2 and DMOG.Western blotting showed that HIF-1 αlevels in PC12 cells treated with CoCl2,DFO or DMOG were higher than that in control group.ELISA analysis showed that SDF-1 α expression was significantly lower in PC12 cells treated with DFO,CoCl2 or DMOG.Conclusion Prolyl hydroxylase domain (PHD) inhibitors up-regulate the level of HIF-1 α and down-regulate the level of SDF-1α in rat pheochromocytoma PC12 cells.关键词
